Fraggy_the_undead writes: according to German IT news site heise.de (German, google translation), yesterday several 3D-showings of "Avatar" couldn't take place, because the movies were DRM protected in a way, that there had to be a key per copy of the film, per film projector and per movie server in the theater. The keys supplier by the name Deluxe was apparently unable to provide a sufficient number of valid keys in time.Moviegoers were offered to get a refund or view an analogue 2D showing instead.
